Lunchbox Jigsaw

I packed her lunch that morning, water bottle, red apple, a tub of grapes, ABC Muffin, a packet of popcorn and a vegemite sandwich. Will it be enough I wonder? At pick up time she leaves the classroom, hair ruffled and clothes bedraggled after a hard day learning and playing. “I’m hungry, do you have food?” she asks, I say hello. The next day I pack her water bottle, a frozen yogurt, carrot, banana, two chocolate chip biscuits, and a cheese and bacon roll. At pick up time, she wanders out of the classroom, hugs me hello and says “I didn't have enough to eat, do you have food?” The day following I pack her water bottle, a frozen yogurt, carrot, red apple, banana, hot cross bun, and a vegemite sandwich. At pick up time, she comes out of the classroom, I can hear her tummy rumbling from where I’m standing. A bag of afternoon tea snacks is already in my hand before she asks. Trying again the day after I pack her water bottle, frozen yogurt, carrot, red apple, 2 slices of leftover pizza and a vegemite sandwich. I go into school at lunchtime, she is eating everything herself and it is all demolished, practically inhaled she is so hungry. And thusly back to the lunchtime jigsaw puzzle I go, how much food CAN I fit into one lunch box? Note: Heidi is on 92nd percentile for height and only 67th percentile for weight. I can only assume all that food goes into growing her taller and taller and taller.
